Multiple Choice
All energy in an ecosystem comes from the sun. This energy is passed through the ecosystem as organisms eat other organsims.
5
Multiple Choice
Organisms that produce their own food mostly through photosynthesis (producers). Examples are plants and algae.

Multiple Choice
Organisms that get their energy and nutrition from other organisms (consumers).

Multiple Choice
Animal that gets its energy and nutrition from eating plants.
11
Multiple Choice
An animal that eats other animals is a....
12
Multiple Choice
An organism that eats both plants and animals are know as a
13
Multiple Choice
Heterotrophs that “clean up” the ecosystem by eating dead and decaying organisms.
14
Multiple Choice
Heterotrophs that get energy and nutrition from dead or decaying organisms or their waste products and recycle nutrients back to the ecosystem.
15
Multiple Choice
All of the following are consumers except
16
17
Multiple Choice
The fourth trophic level where animals eat secondary consumers or below.
18
Multiple Choice
The third trophic level where the animals eat herbivores.
19
Multiple Choice
Herbivores--The second trophic level where herbivores eat the primary producers.
20
Multiple Choice
Autotrophs--The bottom trophic level where all organisms produce their own food, usually by photosynthesis.
21
22
Multiple Choice
Matter is passed up the ecological pyramid in a similar way to energy but recycled by decomposers and detritivores. This Biomass pyramid roughly follows the 10% rule as well.
23
Multiple Choice
Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.
24
Multiple Choice
Which organisms in the diagram have the most energy to give to other organisms?

Multiple Choice
What is a food chain?
27
Multiple Choice
What type of organisms are the first step in a food chain?
